Its hard to figure that out without a link, maybe you could paste the code here for more scrutiny. I am wondering if your image is in a table, if it is, then the width should be the same as the total width of the images.

Make sure you've got these set to "0" in your TABLE tag (if you're using TABLEs)

cellpadding
cellspacing
border

Make sure that you don't have extraneouse white space in your TABLE tags like so:

<tr> <td> </td> </tr>

YOur tags should be nested right next to each other. Carriage returns (line breaks) are ok but spaces are not as they count as a "character" and can throw off your alignment. If that still doesn't work then please post a link.
